Wired: Microsoft announced the next generation of Xbox - Xbox One, featuring new Kinect based on ToF sensor. The new Kinect camera is tightly integrated now - the new Xbox does not function without it. It features 1080p30 video and is said to have a vastly improved depth camera that can even detect a heartbeat (from RGB image, it appears) (flash plugin needed):
Update: As said in comments, Engadget publishes Microsoft's CVP Ilan Splillinger explanations on Kinect sensor: "The highlight of the story is the CMOS sensor, which we developed internally. This design was done completely, 100 percent on this site. This is brand-new technology. There is discontinuity between this technology and the first Kinect; from the technology perspective that we are using for depth, for 3D measurement. So this was done here. On this one, this was a complete Microsoft custom design, where our engagement is directly with the manufacturer. It's not with any third party. We did the work. We do the qualification of the parts. We do the validation of the parts. We have done everything on this one."
